Rules of Sudoku 3 Dimension.
This is a new variation of Sudoku 3D, I call this puzzle Sudoku 3 Dimensions in order to distinguish it with my usual Sudoku 3 D. Imagine a big cube composed with 27 smaller cubes, each visible side of the big cube is composed of 9 sides from the smaller cubes. It is possible to put 3 Sudokus on the three flat sides of the big cube. So each 3x3 region of each sudoku will be on a side of the small cube this means that 27 sides of small cubes must be visible to have three Sudokus, like this.
But if one small cube is removed and 27 sides from the small cubes are visible it is again possible to put the 27 regions of 3 different Sudoku on the 27 sides. As the column and row follow the side of each small cube, the column and row will wrap around the new contour. But in any case each region of 3x3 is part on a row and on a column. Each column or row start from the outer edge of the big cube and endfinish at the bold line.
The gist is that if after removing some small cube it remains 27 visible faces from smaller cubes we are able to combine three Sudokus on the configuration. The rules are the same: each column, row and region(box of 3x3) must contain all the numbers from 1 to 9. This is an example of a puzzle and its solution.
